Folate Intake Improves Assisted Reproductive Technology Outcomes

(HealthDay News) — For women undergoing assisted reproductive technology treatment, higher supplemental folate intake is associated with improved outcomes, according to a study published in Obstetrics & Gynecology.

Audrey J. Gaskins, ScD, from the Harvard School of Public Health in Boston, and colleagues conducted a prospective cohort study involving 232 women (median age, 35.2 years) undergoing assisted reproductive technology. 

The researchers sought to examine the correlation of folate with outcomes. A validated food frequency questionnaire was used to assess diet before assisted reproductive technology treatment.

Higher folate intake correlated with higher rates of implantation, clinical pregnancy and live birth, according to the data. With increasing quartile of folate intake, the adjusted percentage of initiated assisted reproductive technology cycles that resulted in a live birth increased (30%, 47%, 42% and 56%; P for trend=.01). 

For women in the highest vs. the lowest quartile of supplemental folate intake, live birth rates were 20% higher. Higher fertilization rates (P for trend=.03) and lower cycle failure rates before embryo transfer (P=.02) were also seen in association with higher supplemental folate intake.

"Higher intake of supplemental folate was associated with higher live birth rates after assisted reproductive technology treatment," the researchers wrote.
